1 o This invention relates to wheeled warehouse trucks and more particularly to such trucks which are known as a dorf box or roving box and is adapted for use in textile mills or factories. In such factories these dofi boxes are used to receive the output of different machines within the mill whereby the same can be transported from diiferent parts of the mill as desired, the boxes being adapted to receive bobbins, spools, quills, yarns and loose bat cotton. i

An object of the invention provides a dofr box having a rectangular base, to the under side of which are attached intermediate its sides tothe front and rear thereof a single wheel, andv two side wheels intermediate the ends of the bottom or base. It will be noted that the two side or intermediate wheels extend slightly downwardly past the lower level of the front and rear wheels whereby the box, when resting on the side wheels, can be easily pivoted or turned end for end. Further, the box can be rocked somewhat on its side wheels to slightly lower the forward or discharge end of the box. y

A further object of the invention is to provide a doit box having the bottom thereof with a forwardly directed inclined slidel extending to substantially the mid-point of the unit and extending from side wall to side wall to thereby ldirect material within the box, as by natural gravitation, to the front `of the box where easy access may be had to the box contents.

A further object provides such a dof b oxwith sides tapering upwardly from frontto rear to take care of or compensate for the space Ioccupied by the tapering insert in the bottom of the box and thereby produce a box of equal capacity to one without the inclined bottom.

A further and important object of the invention provides an opening in the front portion of the bottom of the box, said opening having therein a plurality of spaced transverse rollers which permits dirt, dust and other foreign particles to pass out at the base of the box, the rotation of the rollers caused by the act of removing material from the frontof the box, further` assisting dirt removal.

A further object of the invention provides the front of the box with a vertically slidable wall which is pressed down by the operator in grasping material in the box and thus permits easy removal and easy access to materials within the box, the upper edge of theislidable front plate being provided with a strip of air-foam rubber to prevent injury to the operators liarld-or*armv during theremoyal;operations; n,

11 Claims. (Cl 214-84) Other objects and advantagesv will become apparent to those skilled in the particular art when considered in the light of the following detailed description and drawings in Which- Fig. 1 is a perspective View in side elevation of the roving or do box;

Fig. 2 is a top plan View of the doit box;

Fig. 3 is a horizontal longitudinal sectional view through the box proper;

Fig. 4 is a vertical sectional view on the line 1%-4 of Fig. 3;

Fig. 5 is a horizontal sectional view on the line Fig. 6 is apartial sectional view of a modification in which the forward portion of the handle acts as a stop for the slidable front plate; and

Fig. '7 is a sectional view on the line T-'I of Fig. 6.

Referring to the drawings, in which like numerals indicate similar parts throughout the various views, the doff or roving box is provided with a rectangular base or bottom 6, a rear wall l, two sides and 9, thefront wall consisting of spaced members Ill and I I for a purpose later to be described.

The base has attached to its under side and extending downwardly therefrom a front wheel I2 which is mounted in a U-shaped bracket I3 attached to the base as by screws I4, the wheel being mounted on a bolt I5 forming an axle for the wheel and extending through openings at the lower ends of the bracket. This wheel is mounted adjacent the front end of the truck and substantially equidistant between the two sides 8 and 9: Likewise, and in the same manner, the base is provided with a rear wheel I6 mounted on a U-shaped bracket II attached to the under side of the base as by screws I3. The two side wheels I9 are attached to the base at opposite sides thereof by like U-shaped brackets 2i).

The reari'wall 'I, two sides 8 and 9 and partial front wall I I are placed or attached to the upper side of the base 6 a slight distance inwardly of itscircumference to form a laterally extending circumferential rib 2|. Spaced about midway up the sides, rear and front wall of the box is a `lateral rib 22.

- The base or bottom of the dof box is provided with an opening extending entirely across the same and from about midway of the same to adjacent the partial front wall I0. Within this opening are a plurality of rolls 23 having at each end supporting studs 24 which are journaledv in holes in the respective sides of the base defining the V)recess wherebyV ythe rolls are rotatably` mounted. The inner rear portion of the base has fitted therein a plate which covers the entire rear portion of the base and is tapered forwardly, or from back to front, such tapering producing a bottom sloping toward the front of the box to cause articles within the box to gravitate to the front of the box andvonto the rollers 23. And this .is made more `so by the rocking of the lfront end of the box downwardly on its intermediate wheels I9. A

The partial front walls I0 and Il of the do'i box are spaced to form vertical channels or recesses 26 and 21 which actas guides and into which is placed a vertically sliding front plate lower edge of the front slide is .provided .with two laterally spaced vertically projecting recesses 30 adapted to receive tubular m'etal inserts 3l. The base between the parts I0 and Il has openings 32 and 3B which are in alignment with the recesses 39, the openings having threaded pins 365 extending upwardly therethrough, the lower ends "of the pins below the base having nuts 35 thereon, The openings 33 are countersunk to receive nuts 36 whereby through the nuts 35 and 36 the pins are held in position. Coiled around the pins 34 are compression springs 31 with their lower ends seated in the countersunk portion and their free ends engage the lower edge of the slide 218 to normally urge the same to its uppermost position.

The sides and rear walls havevattached to their upper edges a finishing strip 38, the forward ends of which at each side extend across the upper open ends of the guide slots 26 and 21 to thereby close the same and thus confine the sliding front 28 within the guides and also limit the upward movement thereof under the action of the springs 31. Handle members 39 and 4D are fastened to the upper sides of the finishing strip adjacent the front of the dol box whereby the same can be grasped during pushing or manipulation of the box.

In the modification shown in Figs. 6 and '1 the construction is substantially identical with that of the other figures with the exception that in this modification the finishing strip 38 has been dispensed with or omitted and the handle 4| of Fig. 6 is attached directly to the upper edge of the side il, the front end d'2 of the handle bridging the guide opening for the slidable front 28 to thereby retain the same within the guide.

It will thus be seen that we have provided a very desirable doff or roving box which is well adapted for the use to which it is intended, the same being provided with a vertically movable front wall whereby the same can be lowered to facilitate removal of material therefrom. Further, the box is rockably mounted onthe two 'side wheels permitting the same to easily be rocked to its forward end to lower the same which 'causes the contents therein to gravitate towards the front or discharge end of the box. Such action is further facilitated by the forwardly inclined bottom insert and the rollers, which upon removal of material are caused to rotate and further facilitate movement of material to the front or discharge end of the box, the rollers being laterally spaced in an opening in the box to permit dirt, dust, lint and other `foreign material to drop to the floor and out of the box.
